Hydroxyurea + EPO for Sickle Cell Disease
(ACHiEvE-SCD Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a combination of hydroxyurea and erythropoietin (EPO) to determine their effectiveness in treating chronic anemia in people with sickle cell disease (SCD). Researchers aim to assess the safety of this combination and its ability to boost hemoglobin levels, which are crucial for oxygen transport in the blood. Participants must be adults with a confirmed SCD diagnosis who have maintained a stable dose of hydroxyurea for at least 60 days. As a Phase 1, Phase 2 trial, this research seeks to understand how the treatment works in people and measure its effectiveness in an initial, smaller group.
Will I have to stop taking my current medications?
If you're taking hydroxyurea, L-glutamine, or crizanlizumab, you can continue these medications at the same dose and schedule during the study. However, you should not have taken voxelotor or EPO within 30 days before starting the study drug.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that using erythropoietin (EPO) with hydroxyurea to treat sickle cell disease (SCD) could be safe. In one study, most patients who received this treatment showed improved hemoglobin levels, suggesting effectiveness without major issues.
Some evidence indicates that combining EPO with hydroxyurea helps manage the disease more effectively. This combination might allow for higher doses of hydroxyurea, which could benefit those at higher risk.
However, EPO has its drawbacks. It can sometimes cause problems like blood clots, especially in patients with a history of such issues. Overall, the treatment appears manageable for most patients, particularly with careful monitoring.12345Why are researchers excited about this trial's treatments?
Researchers are excited about using erythropoietin (EPO) with hydroxyurea for sickle cell disease because it offers a novel approach to managing the condition. While standard treatments like hydroxyurea alone or blood transfusions help manage symptoms and prevent complications, adding EPO aims to boost hemoglobin levels more effectively. EPO works by stimulating the production of red blood cells, which could potentially improve oxygen delivery in the body and alleviate anemia more efficiently than current options. This combination treatment might offer a better solution for patients who don't respond well to existing therapies.
What evidence suggests that this trial's treatments could be effective for sickle cell disease?
Research has shown that erythropoietin (EPO) combined with hydroxyurea can help treat anemia in people with sickle cell disease (SCD). In this trial, participants on a stable dose of hydroxyurea will receive increasing doses of EPO. One study found that 87.5% of patients experienced an increase in hemoglobin levels by at least 1.0 g/dL after 12 weeks, suggesting this combination can effectively improve anemia. EPO also benefits those with kidney problems who cannot take high doses of hydroxyurea. Overall, this combination appears promising for managing long-term anemia in SCD.12346

Are You a Good Fit for This Trial?
Adults over 18 with confirmed sickle cell disease (HbSS or HbS/β0-thalassemia), not on blood transfusion programs, and without recent use of certain drugs like voxelotor or EPO. Participants must have been on a stable dose of hydroxyurea for at least 60 days and plan to continue it during the trial.Inclusion Criteria

Trial Overview
The study is testing the combination of erythropoietin (EPO) with hydroxyurea to treat chronic anemia in sickle cell disease patients. It's a Phase 1/2 trial, meaning they're looking at safety and how well it works across multiple centers.

Treatment groups
Experimental Treatment
Subjects on a stable dose of hydroxyurea will be treated with increasing doses of subcutaneous erythropoietin (EPO) as tolerated for an initial 12 weeks, during which the main safety and efficacy endpoints (including the primary endpoint of hemoglobin response) will be assessed. Subjects may continue on treatment for an additional 12 weeks as clinically indicated, with assessment of additional endpoints at the end of the 24-week study period.
Hydroxyurea is already approved in United States, European Union, Canada for the following indications:

- Chronic myeloid leukemia
- Solid tumors
- Thrombocythemia
- Sickle cell syndrome
- Chronic myeloid leukaemia
- Essential thrombocythaemia
- Polycythaemia vera
- Sickle cell disease
